VALVE.

T all whom it may concern Beit known that I, EDWARD E. GOLD, a citizenof the UnitedStates, residing in the borough of Manhattan, city, county,and State of New York, have invented certain new and useful Improvementsin Valves, of which the following is a specification.

My invention relates to valves and is particularly. adapted for'use onsteam valves.

It is illustrated in connection with a qulckacting valve provided with acoarse thread to which it is well adapted.

tion of a valvehaving my invention applied thereto; Fig. 2 is a view atright angles to Fig. l, the handle being shown in section as well as thevalve seat and its connected pipes. Parts are broken away to show thethread. Fig. 3 is a top view of the said device; and Fig. 4 a horizontalsection on the line 4--4, Fig. 2.

In the accompanying drawings my invention is illustrated as applied to avalve which as a whole I designate A, and which has the usual valveheadB and seat C. The valve is carried by the usual stem D which, asillustrated in the broken away portion, Fig. 2, is provided with acoarse or quickacting thread d.

According to my invention means are provided for holding the valve inclosed position and for constantly pressing the same in the direction ofclosing, so that the valve will be held at all times tightly closed.Such means, as illustrated, take the form of a spring member E which ispreferably flattened out, as at e both to increase its spring action andfor ease of attachment. The said spring member E is suitably attached tothe stem D so as to turn therewith, and for this purpose I 'prefer tomake such attachment through the usual handle d1 with which theSpecification of Letters Patent.

stem is provided. This handle has two slots F, which receive bolts' 7whereby by means of suitable nuts and washers the spring member E isadjustably attached to the handle. The lower end or 'toe el of thespring member E is constantly pressed, by reason of its spring action,toward the casing. At Fig. 4 is indicated, by the letter Gr, a recess,which is so located that it receives the spring member E when the valveis closed.` This recess is provided with an inclined wall g, down which,owing to its spring action, thetoe e1 of the spring member E will tendto pass when thevalve is closed, and inasmuch as the spring E is at thistime under tension it will constantly tend to ride down toward thebottom of the recess G and thereby will maintain the valve in closedposition and will compensate for wear on the parts and maintain a tightfit of the valve with its seat, notwithstanding such wear. The said device as illustrated is also provided with means whereby the valve maybe. held against accidental displacement in any position tok which itmay be adjusted, and the said means take the form of a track H locatedperipherally of the casing of the valve A and against which the springmember E is adapted to press with considerable pressure so as to holdthe valve in any position to which it may be adjusted. This pressure,however, is such that the valve may be turned for adjustment. PreferablyI locate the spring member E in the form shown, so that it extendsaxially of the valve and substantially parallel with the stem D; butobviously this arrangement is not essential.

The provision of the coarse thread cl enables me to produce aquick-acting valve 'whereby the valve is opened completely insubstantially a half turn. For this purpose the spring member E may alsoserve as an indicator in connection with the designations Open andClosed as the same appear upon Fig. '4., The dotted line position of thetoe e1 indicates the open position of the valve, whereas the full lineposition in the recess G indicates the closed position. Likewise, inFig. 4, the depending portion of the spring member is shown in dottedlines, in the open position of the valve, and in full lines in theclosed position.

The illustrated form is one of the most desirable forms of my inventionthat are f known to me, but it is not necessarily limited lc'atingmovement and. said inclined surface located at the' end of the,Y travelof said spring finger inthe closing movement of the valve, and inclinedtoward the axis in thedirection of such closing movement of to its seat.

thel valve and said spring finger adapted tok bear on said inclinedsurface when the valve isV seated, whereby the said spring fingerY has atendency to slide down said surface and'maintain -a tight it of thevalve 2.'- A rotary valve having-a 'stema spring member attached to thestem and turning therewith, and means for adjusting said spring lingerrelatively to saidV stem, a casing, and an inclined surface thereonagainst whichjsaid spring'member is adapted to bear, said valve andvalve stem and spring member having a reciprocating movement and saidinclined surface located at the end of the travel of said spiingfingerin the closing movement of the valve, and inclined toward-the axis inthe direction of such closing movement of the 'valve' and saidspring-finger adapted to bear'on saidv incline'd" surface lwhen thevalve is seated,

wherebythe saidgspring finger has a tendencyito slided'own said?sur-face and maintain a tight fit of thevalve to its seat.

3,. A rotary valve having a stem, a spring member attachedV to the stemand turning' therewith, Vacasing, afquick acting threaded connectionbetween said stemand said casing and an inclined Siirfacev onsaidfcasing against.` which said springm'ember is adaptedl to` bear,said .valveand valve stem and spring member having a reciprocatingmovement and' said inclined surface located at the end 'ofthe travel ofsaid spring finger inthe closing movement of the valve, and inclinedtoward the axis in the direction of such' .closing movement of the valveand vsaidrspring `finger adapted to'bear onsaid inclinedsurface'whenthe. valve is seated,

' whereby the-saidspring finger has a tendency. to slide down saidsurface andy maintain a tight fit of the valve to its seat.

A rotary valve having a stem, a casing, a spring member attached to thestem externally of the casing and extending substantially parallel withthe stem and adapted to turn therewith and an inclined surface on saidcasing against which said spring member is adapted to bear, said valveand valve stem and spring member having a reciproeating movement andsaid inclined surface located at the end of the travel of said springfinger in the closing movement of the valve, and inclined toward theaXis in the direction of such closing movement of the valve and saidspring linger adapted to bear on said inclined surface when the valve isseated, whereby the said spring finger vhas a tendency to slide downsaid surface and maintain a tight fit of the valve to its seat.

5. A rotary valve, a casing, a valve stem, a spring member attached tothe stem, a track for said spring member upon said casing on which saidmember presses in adjusting the valve whereby the valve is held inadjusted position, said valve, valve stem and said spring member havinga reciprocating movement, and a recess in said track at substantiallythe end of travel of the spring finger in the closing movement of thevalve, said recess having a wall forming a portion of said track andinclined axially'therefrom and said spring finger adapted to rest onsaid inclined wall when the valve is seated, whereby the spring fingerhas a tendency to slide down said surface and maintain a tight t of thevalve toA its seat.

6. A rotary valve having a reciprocating movement, a casing, anda valvestem, a spring member on one of said last two mentioned parts and theother of said two parts having a surface inclined in the direction ofthe'closing movement of the valve, said spring memberradapted to bearagainst said inclinedl surface when the valve is seated and tending tomaintain a close it of the valve to its seat.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
